The highest Forest stratum, which reaches 30 meters in height, includes adult trees that form an uninterrupted roof of ramifications and dense foliage. This is the stratum that filters and administers the right amount of sunlight to the lower strata.

The smallest trees, between 3 and 10 meters high, make up to the so-called intermediate stratum. This layer is characterized by its discontinuous canopy, presence of young trees that will renew the forest, several fruit trees, bamboos and arborescent ferns.

The lowest stratum, up to 3 meters from the ground, receives little sunlight. Broad-leafed grasses, a large number of smaller ferns, and non-woody plants like begonias are abundant. This vegetal group covers and dresses the forest ground.

Other characteristics of this forest are the presence of two palm species, Pindo (Syagrum romanzoffianum) and Palmetto (Euterpe edulis), the latter being endangered; there are also a number of bamboos that proliferate between the low and the intermediate strata of the forest. Tacuara Guazú (Guadua angustifolia), with its 30 meters in height, is outstanding.

It is important for the bird-watcher to know the tree species of the forest that he is visiting, since most bird species find shelter to nest in certain trees; frugivorous species, for example, concentrate at certain time and on certain trees in a daily search for food, mainly wild fruits. Knowing the ecology of forest trees and how to identify them is an essential tool for all bird watchers. Bird abundance in this natural district is relevant.

In the area of the central marsh in the Reserve, we can see Limpkin, Muscovy Duck, Green Ibis at twilight, always an Everglade Kite, and Wattled Jacana. Also, Slaty-breasted Wood Rails often flying across the roads of these area.

When navigating down the San Francisco Stream, we go through its galleries to identify Rufescent-Tiger Heron, the elusive Sungrebe, Greater Ani, Swallow-tailed Manakin, White-browed Foliage-Gleaner, White-winged Swallow and River Warbler.

The garden areas surrounding the lodge are ideal to comfortably observe Blue-winged Parrotlet, Scaly headed Parrot, Red-capped Parrot, Scale-throated Hermit. Violet-capped Woodnymph, Chestnut-eared Aracari, Plush-crested Jay, some Swallow-Tanagers. We can make a close observation of Purple-throated Euphonia and the Chestnut-bellied Euphonia, Magpie Tanager, Hepatic Tanager, the noisy Red-rumped Caciques and the Epaulet Orioles.

When floating down the waters of the Iguazú River, we can see Black-collared Swallow and White-winged Swallow, Herons, Kingfishers and probably some birds of prey.

In the plantations and grassland areas near Yacutinga Wildlife Reserve, we can observe Tataupa Tinamou and Small-billed Tinamou, Plumbeous Kite, Pale-vented and Picazuro Pigeons, Striped Cuckoo, White-eared Puffbird, Tawny-crowned Pygmy-Tyrant, Yellow-bellied Elaenia and the impressive Red-crested Finch. Maybe we can enjoy the high flight of a King Vulture, surely Turkey Vulture and Black Vulture. Also, Great Dusky Swift, Ashy-tailed Swift; in summertime a group of Swallow tailed Kites, and some eagles.

The location of Yacutinga Wildlife Reserve belongs to the phytogeographical area of the Parana Forest. This is one of the most bio-diverse areas in Argentina.

The main characteristics that generate this exuberant Nature are its warm climate, constant humidity, and the lack of dry seasons and of changing climate.

These environmental conditions make the area a sort of giant greenhouse. This is a completely green, stubborn and many a times, impenetrable forest. The forest structure becomes apparent in its different plant strata, which provide more than 320 bird species listed in Yacutinga with shelter, food and reproduction sites.
